PASSAGE

When we imagine a forest, we think of green plants, shrubs, algae, insects, animals, butterflies, mushrooms, flowers, creepers and many more living beings that lend vibrancy to this wonderful aspect of nature.

Dead trees are referred to as ‘snags’. What happens when a tree dies in the forest? No one removes it, let alone destroys it, by burning or burying, it is just left to be. Of what good is a dead tree? Well, when a tree dies, the tree itself may have ceased to live, but it continues to foster the intricate ecosystem of biota that is truly enthralling. A dead tree is a valuable habitat for a host of other species like birds, insects and reptiles. It hosts algae, lichen and moss, which in turn provide food and sustenance to a host of other organisms. That is why in informed societies where forests are part of conservation plans, dead trees - whether standing or fallen - are left undisturbed to exist cheek-by-jowl with other constituents of the forest. A tree that has been dead for a very, very long time might start disintegrating with sustained response to sunlight, rain, moisture and wind. Even as it disintegrates, it turns into valuable compost with minerals and roughage that enriches the soil of the forest.

The Northern Illinois Forestry Association lists atleast 38 species of birds `` that sceavate nest holes or use existing holes in dead or dying trees are 29 species of mammals that use tree cavaliers for various purposes ”.
